Figure and Figure Legend
Figure and Figure legend sometimes are more IMPORTANT than main text, because many senior readers read figures first.
Check first and last sentence in the whole paper. To make it easy to read, in every paragraph, first and last sentences are important. Usually, first sentence introduces and summarizes the whole paragraph; last sentence concludes the whole paragraph (e.g. “This result suggests that …”).
Check sentence patterns (Useful Sentence Patterns):
performed RT-qPCR (RNA-seq …) for … → XX was validated (seqenced …) by RT-qPCR.
built a Random Forest model … → We used/developped a Random Forest model to …
We assayed/analyzed … datasets.
We curated/collected … datasets from … OR 100 datasets were curated/collected from …
XX was significantly enriched in the noncoding sequences (t test P-valeue: 0.002).
The enrichment is/was calcuated with RNApromo (ref.). The P-value cutoff is/was 0.001; the xx is/was 0.5; the xx is/was 0.8. (depends on if you are talking to the audience about a plot or describe a result you have done.)
